To simulate the time required by each UAV \(j\)  to convolve two vectors, say \(e_1 \in \mathbb {R}^{n_1}\)  and \(e_2 \in \mathbb {R}^{n_1}\) , we adopt the following shifted exponential distribution model commonly used in the literature [1]}:
\(\mathrm {Pr}[T^{comp}_{j}(e_1, e_{2}) \le t] = 1 - e^{\frac{\mu _{j}}{c(n_1,n_2)}(t - \alpha _{j}c(n_1,n_2))} \nonumber \)
